Abstract: Disclosed is a fire extinguisher comprising a container separated into two compartments, one compartment containing pressurized gas and the other containing an extinguishant. The container has a valve to release the extinguishant, which is forced from the container when the bladder is expanded by the pressurized gas. The center of the bladder has a force absorbtion means for protection against the impact of the bladder striking the inner wall of the container. The force absorbtion means has two disks clamped together to retain an annular bead of the bladder.
